Light Is the Enemy of Deep Sleep. This Eliminates It.
Even small amounts of ambient light — a streetlight through the curtains, a charging indicator, a hallway glow under the door — suppress melatonin and fragment your sleep architecture without ever fully waking you. You lie there wondering why you don't feel rested. The room looks dark enough. It isn't.
The Mulberry Silk Sleep Mask creates complete, pressure-free blackout regardless of your environment. 100% mulberry silk against your skin — the same material used in luxury bedding — stays temperature-neutral through the night instead of trapping heat like foam or polyester alternatives.
Why It Works
Total blackout construction blocks 100% of ambient light — streetlights, device indicators, early sun
Mulberry silk is temperature-neutral and breathable — no heat buildup across a full sleep cycle
Contoured design creates an air pocket over the eyes — no pressure on lids or lashes, works for side sleepers
Adjustable strap fits all head sizes without leaving marks or slipping during the night
In the Rest Theory Stack
This product addresses: Light
Light is the primary circadian signal. Eliminating it at the source is the single highest-leverage change most people can make to their sleep environment. Pair with Blackout Curtains for full room coverage, or use the mask alone for immediate impact anywhere you sleep.
